Hello,
Regarding moving the dial - if you drop the dial on the "gear icon" you will be able to choose "Insert above/right/left/below" which will move in a row and place the dial there. But it will also resize group (add row/column) if there is not enough space.
I will be adding new "Dynamic mode" soon that will make things work similarly to other popular addons so there it will work as you expect. I will try to add it next week.

Regarding Pro version, please write me to my support email what exactly do you have in mind and I'm sure we can think of something.

Best regards,
Juraj Mäsiar
